Fruit & Veggie Pesticide Residue Test Results



Are you growing your own vegetables and fruit or do you need to purchase them from grocery stores? The U. S. Department of Agriculture tests produce every year. Do you know that 65% of produce samples in recent tests contained pesticide residue?

After analyzing the data from USDA and FDA tests, the Environmental Working Group has produced a Shopper’s Guide to Pesticides in Produce™ containing test results from 48 popular fruits and vegetables. This report classifies those with the most pesticides as the “Dirty Dozen PLUS™”. The most contaminated fruits are Peaches, Apples, Nectarines, Strawberries and Grapes.The vegetables include Sweet Bell Peppers, Hot Peppers, Spinach, Cucumbers, Cherry Tomatoes, Snap Peas, Potatoes, Celery and Kale/Collard Greens.

Of note, all the nectarines and 99% of the apples tested positive for at least one form of pesticide; and a single sample of grapes tested positive for fifteen pesticides. The average potato sample tested more positive for pesticides by weight than any other food. If these are favorites on your list, consider buying organically grown. Kale/Collard Greens and Hot Peppers tested positive for pesticides that are toxic to the human nervous system.

The report also includes a list of produce with the least pesticide concentration, they are referred to as the “Clean Fifteen™”. The least contaminated fruit are Avocados, Pineapples, Mangoes, Kiwi, Papayas, Watermelon, Grapefruit and Cantaloupe. The veggies include Onions, Cauliflower, Asparagus, Sweet Peas, Cabbage, Eggplant and Sweet Potatoes. Avocados were the cleanest and over 80% of pineapples, kiwi, papayas and mango had no pesticide residue.

Use this report to shop smarter as you enjoy healthy fruit and vegetables in your diet. Remember to peel or wash them well before eating.

Dehydrating Apples in a Sun Oven®

Apple harvest time this year produced lots of fruit. We canned slices, made apple sauce and dried some. The SunOven® works well as a fruit dehydrator. First we set the SunOven® outside, but not focused on the sun. We wanted a slight preheat but to less than 100º.   Apples were washed and aligned in a Norpro “Apple Master”, an apple peeler, corer, and slicer. A few turns of the handle made quick work of the first apple. Slide the apple spiral slices off the core and place them on a cutting board.

Slice the spiral in half.  Place the apple slices in a solution of water and Fruit Fresh® ascorbic acid (follow directions on bottle) to keep the slices from turning dark.

Cover the drying racks with parchment paper and drain apple slices. Line them up on the racks. Carefully arrange the racks inside the SunOven®. Leave the door latches under the glass door to allow air flow and keep the temperature low inside. We turn the oven so it is behind the sun track. Check at the end of the day. If not completely dry, latch and leave over night. Finish the next day. When slices are dry, remove from racks and pack into a clean glass jar. Add an oxygen absorber and pull a vacuum with a Food Saver® or by hand with a clean brake bleeder. Store cool and dark.

Sun Oven Accessories

Over the years that I’ve been using my Global Sun Oven I’ve come up with countless creative ways of stacking all sorts of baking pans to make the most of the space in the cooking chamber. Some attempts were more successful than others; the main issue was always slippage.

In fact, apart from a batch or two of tomatoes per year, I’d pretty much given up on solar food dehydrating. It was just too much hassle to fit enough stuff in the Sun Oven to justify tying up it for a whole day.

So, of course, as soon as I received my set of Sun Dry Dehydrating Racks I had to put them to the test. So what if it was already noon and the only produce I had on hand were three tiny apples. I had a new toy and I wanted to play with in now. Turns out I only had enough fruit for two layers and enough remaining hours of sunlight to get the job half done (I finished up the next day), but I could see right off the bat the slippage was a thing of the past.

The racks fit snuggly on top of each other and leave plenty of room for airflow allowing both layers to dry out at the same rate. The hardest part is keeping the Sun Oven from overheating, get distracted for too long and it will easily reach 200F or more, even with the glass door propped open. It’s a good idea to set a timer and check on it every half hour or so.

Easy Solar Side or Dessert

This fruit sauce makes a good side for pork chops, or can be topped with whipped cream for an easy dessert. It’s also good on vanilla ice-cream or on it’s own as a snack. Pretty much any kind of apples or pears can be used so get the ones that are on sale.
